Dating the moon-forming impact event with meteorites
more »
Through a combination of data analysis and numerical modeling work, researchers have found a record of the ancient moon-forming giant impact observable in stony meteorites. The research indicates numerous kilometer-sized fragments from the giant impact struck main belt asteroids at much higher velocities than typical main belt collisions, heating the surface and leaving behind a permanent record of the impact event.

Giant galaxies die from the inside out: Star formation shuts down in the centers of elliptical galaxies first
more »
Astronomers have shown for the first time how star formation in "dead" galaxies sputtered out billions of years ago. Astronomers have revealed that three billion years after the Big Bang, these galaxies still made stars on their outskirts, but no longer in their interiors. The quenching of star formation seems to have started in the cores of the galaxies and then spread to the outer parts.

Dwarf planet Ceres color map reveals surface diversity

A new color map of dwarf planet Ceres, which NASA's Dawn spacecraft has been orbiting since March, reveals the diversity of the surface of this planetary body. Differences in morphology and color across the surface suggest Ceres was once an active body.

Proto-suns teeming with prebiotic molecules
more »
Complex organic molecules such as formamide, from which sugars, amino acids and even nucleic acids essential for life can be made, already appear in the regions where stars similar to our Sun are born. Astrophysicists have detected this biomolecule in five protostellar clouds and propose that it forms on tiny dust grains.

Scanning meteorites in 3D may flesh out solar system’s origin story
Science Focus
original post »What’s in a rock? A few mineral deposits, maybe a ring of metal—and, possibly, a snippet of the Solar System’s origin story.
That’s the premise under which a team of researchers at the American Museum of Natural History in New York City is operating. By conducting three and two-dimensional image analyses of rocks brought to Earth from space, these scientists hope to demystify the elemental formations that birthed the planets we know today.
Denton Ebel, chair of the AMNH’s physical sciences division, explained that much of our understanding of the inchoate Solar System can be gleaned from studying chondrites, which are stony meteorites that contain molten droplets of minerals. Unlike most meteorites at the time of the Solar System’s formation, chondrites never joined a large planet or underwent extensive physical maturation; thus, they’re one of the most primitive forms of mass from the Solar System in existence, rendering them ideal candidates for this area of study.

Red Supergiant Star V838 Monocerotis Star Stickers
Here's a great sheet of stickers featuring a beautiful image from deep space
tagged with: amazing astronomy images, hubble images, monocerotis, supermassive red giant, stars, interstellar dust, swirling dust clouds, monoceros constellation, red supergiant star, fun stickons
Galaxies, Stars and Nebulae series A gorgeous astronomy picture featuring a distant star, named V838 Monocerotis, in the direction of the constellation of Monoceros on the outer edge of our Milky Way. The image shows the swirls of dust spiralling across trillions of miles of interstellar space, lit mainly from within by a pulse of light from the red supergiant, two years into its journey.

One-Armed Spiral Galaxy NGC 4725
more »
While most spiral galaxies, including our own Milky Way, have two or more spiral arms, NGC 4725 has only one. In this sharp color composite image, the solo spira mirabilis seems to wind from a prominent ring of bluish, newborn star clusters and red tinted star forming regions. The odd galaxy also sports obscuring dust lanes a yellowish central bar structure composed of an older population of stars. NGC 4725 is over 100 thousand light-years across and lies 41 million light-years away in the well-groomed constellation Coma Berenices. Computer simulations of the formation of single spiral arms suggest that they can be either leading or trailing arms with respect to a galaxy's overall rotation. Also included in the frame, sporting a noticably more traditional spiral galaxy look, is a more distant background galaxy. Tomorrow's picture: pixels in space

The Sun in the Milky Way galaxy poster

Early explorers mapping the continents of our globe, astronomers are busy charting the spiral structure of our galaxy, the Milky Way. Using infrared images from NASA's Spitzer Space Telescope, scientists have discovered that the Milky Way's elegant spiral structure is dominated by just two arms wrapping off the ends of a central bar of stars. Previously, our galaxy was thought to possess four major arms. This artist's concept illustrates the new view of the Milky Way, along with other findings presented at the 212th American Astronomical Society meeting in St. Louis, Mo. The galaxy's two major arms (Scutum-Centaurus and Perseus) can be seen attached to the ends of a thick central bar, while the two now-demoted minor arms (Norma and Sagittarius) are less distinct and located between the major arms. The major arms consist of the highest densities of both young and old stars; the minor arms are primarily filled with gas and pockets of star-forming activity. The artist's concept also includes a new spiral arm, called the "Far-3 kiloparsec arm," discovered via a radio-telescope survey of gas in the Milky Way. This arm is shorter than the two major arms and lies along the bar of the galaxy. Our sun lies near a small, partial arm called the Orion Arm, or Orion Spur, located between the Sagittarius and Perseus arms.

Carina Nebula, Star Forming Gas-cloud Sculpture Stickers
Here's a great sheet of stickers featuring a beautiful image from deep space
tagged with: billowing interstellar gas clouds, cnbigc, star forming activity, carina nebula, amazing space sculpture, star nurseries, stellar winds, young hot stars, gas cloud sculpture
Galaxies, Stars and Nebulae series A beautiful space photograph featuring the 7500 light year distant Carina Nebula. This Hubble image shows rich, interstellar gas clouds feeding the formation of new stars. As a proto star forms, the gas clouds get dragged to its surface and some gets emitted as tight jets of material travelling at hundreds of miles per second. These in turn help sculpt the gas clouds into weird and grotesque shapes, some looking like strange worms, swimming through space.
